Shattering the Efficacy Ceiling in
Immune-mediated Inflammatory disease

Our Mission

To clinically advance ELN28, our lead first-in-class, dual-acting soloMER conjugate that combines two clinically proven agents – positioning it as a truly transformative therapy for Hidradenitis Suppurativa.

our Vision

To lead the next wave of innovation in immune-mediated diseases – developing therapies that transform patient outcomes and redefine clinical practice.

about elasmogen

Elasmogen is a privately held biopharmaceutical company leading the next wave of innovation in immune-mediated inflammatory disease.

Our ADC-inspired approach combines biologic precision with localised small molecule activity, creating safer, more effective treatment.

Hidradenitis Suppurativa is a deeply impactful disease, causing significant physical and emotional distress that requires a comprehensive, long-term approach to manage, often involving both medical and surgical strategies.

Hidradenitis Suppurativa – A MAJOR UNMET NEED

 

HS is a chronic inflammatory skin condition characterised by painful lesions, deep nodules, abscesses, skin tunnels, and scarring, typically affecting the axilla, groin, perianal, and inframammary regions. Beyond physical discomfort, HS has profound psychosocial impact.

Current biologics help fewer than half of HS patients and importantly do not stop disease progression. This means that many patients rely on repeated surgeries to try and reduce the disease’s impact.

Our team has designed ELN28 specifically to meet this need, with the potential to deliver the safest and most effective treatment for HS.

ELN28: Precision Immunosuppression

 

ELN28 is a first-in-class, dual-acting soloMER conjugate combining two clinically proven agents. Its innovative design brings together targeted TNFα blockade and localised JAK inhibition, improving efficacy while reducing systemic exposure.

 

    • Dual-action: TNFα blockade plus JAK inhibition for greater efficacy.
    • Precision molecular engineering targeting extracellular and intracellular disease drivers.
    • Innovative linker design provides tailored, inflammation-driven JAKi release exactly where it is needed.

Efficacy

The combined anti-TNFα and JAKi activities deliver additive benefit in robust preclinical models.

Safety

Preclinical data confirms site-directed JAKi delivery, enabling precision immunosuppression confined to diseased tissue.

Translation

Neutrophil-driven JAKi release has been demonstrated in human cells and patient tissues.

 

Market Opportunity

The HS market is a rapidly expanding (~16% CAGR) and is expected to grow from its current ~$2 bn size to over $8 bn in the next 10 years.

Current approved therapies show meaningful clinical response in ~30% of patients providing an opportunity for a more efficacious drug such as ELN28.
